To all whom itnnay concern:

vBe it known that i I, FRANCIS M. TA'NEY- HILL, a citizen of the United States, residing at Barnesville, in the county of Belmont and State of Ohio, have invented certain new and useful Improvements in' Mining-Oar Wheels and in the Oil-Boxes to Same; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon,which form a part of this specification.

Myinvention relates to that class of carwheels in which a series of oil-chambers or lubricant-receptacles areformed in the hub of the ducting the oil to the axle or bearing-surface.

The objects of the invention are to provide means for introducing the oil into the oil-receptacles in a simple and easy way, at whatever position the wheel is arrested in its revolution, to prevent its escape when in motion or at rest, and to automatically and regularly feed and distribute the lubricant, and to increase the capacity of the oil-chain hers. These objects are attained by theconstruction and combination of parts to be hereinafter describedand claimed. i

i In coal-car wheels especially, which turn loosely upon their axles, it is found difficult to obtain a suflicient supply of oil for the bearingsurface, as the channels of communication are liable to clog or gum, and even when the oilreservoir is nearl or quite full the oil cannot be fed regularly to the axle, and where but one opening is provided for introducing the oil,

when in the revolution of the wheel the opening stops at the lower side, fresh oil cannot be introduced, and even that already in theoilchamber is likely to escape when the plug or stopper is withdrawn.

' My invention consists in providing a series of four oil-receptacles projectingfrom the front of the hub, each furnished with an opening and screw-plug, and communicating with the oi-l-chambersin the hub of the wheel, and each of said chambers communicating with each other, so that one of said oil-receptacles will always be at the top of the hub, no matter in what position the wheel stops; and, further, in a series of openings which allow the oil to pass,in the revolution ofthe wheehfrom one to another of the oil-chambers, and in a series of other openings which permit the lubricant to pass from the'several chambers to the axle or bearing-surface.

In the drawings, wherein similar parts are indicated by like letters in the several figures, Figure 1 is a sectional view, showing the oilchambers, the partitions which separate these chambers, and the openings for the passage of oil to the axle. the line a; w of Fig. 1. Fig. 3 is a cross-section with the reservoirs detached. Fig. 4 is an ex ternal end view of the hub, showing the reservoirs, openings, and plugs.-

The axle G is provided with the usual collars and washers to prevent the escape of the oil at the ends of the bearing-surfaces.

A is the outer rim of the hub of a car-wheel divided into four oil-chambers, B, by the partitions c,whichoil-chambers communicate-with each other by openings d, in, the partitions. These openings are represented in the draw ings as located about the center of the partitions, but may, if desired, be placed next the rim A", or adjacent to the solid hub. The oilchambers B extend nearly the whole length of the hub, and allow for the reception of a large quantity of oil, and the capacity of the several oil-chambers is further increased by forming the outside end of the hub into a series of four projections, a, inclosing reservoirs for oil, b, which reservoirs open into and communicate with the respective oil-chambers B. Each of the oil-reservoirs increases the oil-space, and they are also used as the avenues through which the oil is introduced to the oil-chambers. At the outside of each reservoir 1) is an opening, 9, through which oil may be poured into the reservoirs and thence reach the oil-chambers,

and each of these openings is closed by a screw plug and tap, h. By havingthese fourreservoirs, with their openings, the oil-chambers maybe filled with oil in whatever position the wheels stop, as one of said openings will always be at thetop. The partitions cenlarge to form shoulders which encircle the axle. and

make the solid hub in which the axle plays,

Fig. 2 is a vertical section on ders is a triangular opening, 0, extending nearly the entire length of the bearing-surface, through which the oil passes to lubricate the axle. Groovesfon the inside of the shoulders, extending the whole length of the same, supply oil to the entire bearing-surface. Thus as the four compartments B have intercommunication by and through the openings 61, the oil must flow freely from one to the other of the oil chambers, and the openings under and throughthe shoulders ofthe solid hub, in which the axle plays, permit and compel the passage of the oil to the point of lubrication. These four compartments provide for the lifting of the oil as the wheel revolves, and no matter in whatposition the wheel stops they insure the oil being carried to the entire length of the hearing-surface by and through the openings 01 e and the grooves f.

The wheel is attached to the axle G in the customary manner.

Having thus described the construction and operation of my car-wheel and lubricator,what 1 claim therein as new, and desire to secure by Letters Patent, is-

1. The combination, in a car-wheel, of the projecting reservoirs b, provided with the openings g and the screw-taps h, with the oil-compartments B, constructed and operating substantially as described.

'2. Ina car-Wheel, the hub having rim A and partitions 0, whereby the said hub is divided into four equal compartments, B, in combina tion with the projections a, containing reservoirs b, communicating with the compartments 35 B, and provided with the openings 9 and screwtaps h, substantially as set forth.

3. The combination of the oil-compartments B, having partitions 0, provided with openings d, and shoulder havingopenings e and grooves 40 f, with the projections at, having reservoirs b, openings and screw-taps h, substantially-as set forth.

4. The combination, witha car-axle, of the wheel-hubsurroundingthesame,havingshoul- 45 der or hearing provided with openings 6 and grooves f, the said hub being divided by partitions c intofour compartments, B, and the reservoirs b, communicating with said compartments, and provided with means, snbstan- 5o tially as described, for filling both reservoirs and compartments with oil, substantially as set forth.

In testimony whereof I atfix my signature in presence of two witnesses.
